The Airbus A220 is now getting more widely established in service.  Indeed, the slightly smaller and highly efficient nature of the jet means that it is likely to be pretty popular as service gets reestablished for a lot of airlines.  Sadly, I haven’t seen any other than those with Delta.  I have seen a decent number of those, though.  As a continuation of my lockdown trawl of the archives, here is a variety of shots of Delta’s A220 flight.  If you prefer to call this a C Series from its Bombardier days, feel free but that ship has sailed!
